- Fernandez, L. G., Matthews, M. R., & Kim, P. J. (2023). A synthetic hybrid-scale fiber matrix for complex surgical wounds: consensus guidelines. Wounds : a compendium of clinical research and practice, 35(5), E160-E168.More infoBased on their own clinical experience and review of the available peer-reviewed data, the authors developed a consensus opinion on the use of an SHSFM for open wounds. The matrix has features such as varying pore sizes and fibers (ie, hybrid-scale) and is indicated for the treatment of open wounds. This report describes the design and utility of the SHSFM, its mechanism of action, and the methods of application, as well as clinical outcomes. The authors discuss their own experience and review of the published literature, then describe their protocols and rationale for the use of the SHSFM. These consensus statements include recommendations regarding appropriate wounds for use of the SHSFM, use of other wound therapies in conjunction with the SHSFM, reapplication rates, preparation methods, and additional discussions of appropriate use. This report is not a literature review, but rather is a statement of preliminary clinical experience. The consensus statements indicate that the SHSFM may be used to treat a variety of wounds and can be used to stage wounds to closure via skin grafts or by secondary intention.

Wounds : a compendium of clinical research and practice, 35(8), E248-E252.More infoLarge soft tissue defects resulting from trauma in the pediatric population are common. MLLs are a rare subset of these injuries with no standard treatment regimen. Thorough surgical debridement of these lesions is often warranted to remove necrotic tissue and contamination, which results in a large, open soft tissue defect. STSGs may be used to provide tissue coverage; however, they have limitations, including donor site morbidity and additional surgical time and cost.

Early experience and recommendations for the use of an automated estimator of solution volume for negative pressure wound therapy with instillation. Wounds : a compendium of clinical research and practice, 35(2), E82-E87.More infoNPWTi is a device that combines the benefits of traditional NPWT with periodic irrigation. This automated device allows for preprogrammed cycles of dwelling of a solution and negative pressure onto the wound surface. Its adoption has been hampered by the perceived difficulty of estimating the volume of solution needed per dwell cycle. A new software update includes an AESV that makes this determination for the clinician.

The sandwich technique for quick and efficient application of negative pressure wound therapy to the feet and hands: a case report. Wounds : a compendium of clinical research and practice, 35(1), E17-E21.More infoNPWT is a surgical dressing that combines polyurethane foam with the subsequent application of continuous or intermittent negative pressure. NPWT facilitates granulation tissue production by macrostrain, microstrain and, if desired, fluid instillation. Sealing the polyurethane foam over the wound bed is achieved using acrylic drapes; however, this can be difficult to use in some anatomic sites. Failure to achieve an effective seal can necessitate additional supplies, which has led to increased innovation in developing a more effective NPWT seal over the target wound bed. Obtaining an effective pressure seal on the feet or hands can be difficult because these anatomic sites have distinct curvature for each digit, with multiple interdigital web spaces and independent mobility. In this case report, the authors propose a technique to apply either an acrylic drape or combination acrylic and soft silicone drape utilizing the "sandwich technique" to seal NPWT foam quickly and efficiently to the feet or hands.

Plastic surgery (Oakville, Ont.), 31(3), 229-235.More infoBurn center patients present not only with burn injuries but also necrotizing infections, , frostbite, toxic epidermal necrolysis, chronic wounds, and trauma. Burn surgeons are often faced with the need to amputate when limb salvage is no longer a viable option. The purpose of this study was to determine factors which predispose patients to extremity amputations. This retrospective registry review (2000-2019) compared patients who required upper extremity amputations with those who did not. Cases were pair-matched by age, sex, percent total body surface area (%TBSA), and type/location of injury to control for possible confounding variables. There were 77 upper extremity amputee patients (APs) and 77 pair-matched non-amputees (NAPs) with the median age 45- and 43-years, %TBSA 21 and 10, respectively; second and third degree burn injuries were similar in the 2 groups. The AP group had longer hospitalizations (median 40 vs 15 days)
